Precautions for product installation and replacement:
Shut down the unit, recover the refrigerant, and fully depressurize the system before disassembly; do not disassemble or install the safety valve while the system is pressurized, as this poses a risk of injury from refrigerant discharge.
The valve must be installed vertically with the arrow pointing outward; horizontal or inverted installation can cause the valve disc to shift under load, resulting in an inaccurate opening pressure.
Apply thread sealant specifically designed for refrigeration systems to the threads; do not use excessive PTFE tape, as fragments could enter the system and obstruct the valve disc.
Do not tamper with the lead-sealed adjustment nut at the top; unauthorized alteration of the opening pressure compromises safety protection and will result in failure during the annual inspection.
After installation, pressurize the unit to check for leaks, ensuring there is no refrigerant leakage at the valve outlet or threaded base.
Conduct an annual manual inspection of the valve for corrosion, leakage, or damage to the lead seal; replace the valve immediately if any defects are found.

Core Function and Purpose:
Ultimate physical explosion-proof protection against condenser overpressure (highest safety priority)
If system pressure exceeds 1.3 MPa due to fan failure, loss of cooling water flow, refrigerant overcharge, or pipeline blockage, the valve disc automatically opens to release refrigerant. This lowers the internal pressure of the vessel, preventing catastrophic safety incidents such as the bursting of the condenser or liquid receiver and the high-pressure spray leakage of refrigerant.
Completely independent of the electronic control system; provides redundant protection
Operation is unaffected by failures of high-pressure electronic sensors, the main control board, or mechanical high-pressure switches. Even if all electronic protection systems fail, the valve can independently perform pressure relief and system shutdown. It is a mandatory safety accessory for pressure vessels.
Automatic reseating; seals automatically once the fault is cleared
When the high-pressure hazard is eliminated and pressure drops to 1.04 MPa, the spring forces the valve disc to close automatically. No manual reset is required; the unit can be restarted immediately after the fault is resolved.
High-flow, full-lift pressure relief with no lag
Features a large DN25 full-bore discharge path to rapidly release excess pressure, preventing equipment damage caused by continuously rising pressure.
